Device self-calibration and component resolution

ABSTRACT

Events generated from a terminal are analyzed and a problem associated with a component peripheral of the terminal is identified. Operations and parameters to the operation are obtained to resolve the problem. The operations and parameters are encoded in a code along with security information. The code is provided to a mobile device. The mobile device provides the code back to the terminal. The terminal verifies the security information from the code and decodes the operations and parameters. The operations with the parameters are processed to resolve the problem on the terminal, and the security information and code are logged for auditing.

BACKGROUND

A number of technologies exists for managing problems encountered by network devices. Some of these technologies permit remote diagnosis and remote login to a device for resolution. However, certain types of devices are subject to more oversight and regulations than other devices, such as transaction devices.

With transaction devices, device calibration may be required during problem resolution and manually verified by an engineer physically present at the device; sometimes documented evidence must be provided by an engineer to indicate how the device was serviced and how the problem was resolved.

This is inefficient and time consuming for organizations that are required to provide maintenance and support of the transaction devices and results in minor problems that can cause the transaction terminals to be offline and inaccessible to customers for extended periods of time while the appropriate service engineer is dispatched to the problem devices.

Some problems encountered by transaction devices can be resolved by simply reapplying standard calibration settings to the devices, but the settings have to be manually verified after being applied by designated device-support personnel that are present at the devices. Unfortunately, retailers do not employ device-support personnel and typically rely on third-party support vendors; further, the lack of employed support personnel is likely intentional on the part of the retailers in order to limit retailer liability and to maintain service agreements with device manufacturers.

Since customers are performing transactions on transaction devices, procedures, regulations, and sometimes laws require proper authentication and documentation when such settings are re-applied to ensure that retailers are not engaged in fraud against their customers. For example, fuel pumps dispense fuel based on calibration of the fuel-flow rates being dispensed, if it is not document and verified when the pump was recalibrated, how it was recalibrated, and by whom recalibration was performed, the retailer may be accused of fraud if the fuel amount being charged to the customer does not match what is actually dispensed when randomly tested by regulators. The same is true with produce scales interfaced to Self-Checkout stations that weigh produce at a defined price per pound. In fact, there are a variety of peripheral measuring devices associated with transaction devices, which when recalibrated require proof that the proper calibration steps were processed by only authorized personnel.

SUMMARY

In various embodiments, methods and a system for device self-calibration and component resolution are presented.

According to an aspect, a method for device self-calibration and component resolution is presented. A code is obtained from a mobile device and security information that encoded in the code is verified. Operation and parameters encoded in the code are identified and the operations with the parameters are processed on a terminal to resolve a problem being experienced on the terminal. The operations with the parameters and the security information are logged on the terminal.

DETAILED DESCRIPTION

FIG. 1 is a diagram of a system 100 for device self-calibration and component resolution, according to an example embodiment. It is to be noted that the components are shown schematically in greatly simplified form, with only those components relevant to understanding of the embodiments being illustrated.

Furthermore, the various components (that are identified in the FIG. 1) are illustrated and the arrangement of the components is presented for purposes of illustration only. It is to be noted that other arrangements with more or less components are possible without departing from the teachings of device self-calibration and component resolution presented herein and below.

The system includes a transaction terminal 110, a server 120 and a plurality of operator mobile devices 130. Each device 110, 120, and 130 include their own processors and non-transitory computer-readable storage media comprising executable instructions representing: 1) for terminal 110: a code processing manager 111, a code verifier 112, a peripheral driver agent 113, a component event agent 114, and a plurality of peripheral devices 115; 2) for server 120: a terminal event manager 121, a code generator 122, and an operator manager 123; and 3) for mobile device 130: a code agent 131.

The executable instructions when executed by the processors of the corresponding devices 110, 120, and 130 perform the processing discussed herein and below with respect to: code processing manager 111, code verifier 112, peripheral driver agent 113, component event agent 114, peripheral devices 115, terminal event manager 121, code generator 122, operator manager 123, and code agent 131.

It is noted that although a single terminal 110 is illustrated that this is done for illustration as a single enterprise/store may deploy multiple terminals 110 managed by server 120 in connection with a plurality of operator mobile devices 130.

As will be demonstrated more completely herein and below, system 100 permits self-calibration and/or self-component resolution of peripherals 115 for terminal 110 in a manner that is verifiable, secure, and capable of being audited for purposes of complying with any existing regulation or procedure and without requiring only designated support personnel associated with a support organization that services the terminal 110 to be physically present at terminal 110 during calibration or component resolution.

During operation of terminal 110, component event agent 114 reports peripheral events to terminal event manager 121. These events are with respect to operation, actions, state, and status of peripherals 115 and terminal 110. Terminal event manager 121 determines based on the events when a problem is encountered requiring service. Each problem is mapped to a predefined set of operations that have to be processed on terminal 110 in order to resolve a specific problem. If the set of operations, do not require any verification or in-person service audit trail of a service personnel applying the operations to terminal 110, terminal event manager 121 may send the operations over a network connection to peripheral driver agent 113. Peripheral driver agent 113 then processes the operations on terminal 110 to resolve the problem.

However, when the type of problem is associated with a peripheral 115 that requires verification of auditing of an authorized support person, then terminal event manager provides the necessary operations to code generator 122. Code generator 122 encodes the operation along with security verification information that can be authenticated and verified by code verifier 112. The security verification information 112 provides audit information that can be mapped back to terminal event manager, the identified problem, the events that precipitated the problem identification, and the operations that need to be performed on terminal 110 to resolve the problem.

The encoded operations having the security information are provided from code generator 122 to operator manager 123. Operator manager 123 maintains a list of staff present at terminal 110 for a retailer along with a mobile device identifier or email address. The encoded operations with the security information are sent to code agent 131 of a registered device 130. Code agent 131 then communicates the encoded operations having the security information to code verifier 112 of terminal 110. This communication can be through a Near Field Communication (NFC) tap or by displaying the encoded information with security information as a Quick Response (QR) code a display of device 130 where an operator of device 130 presents the encoded information with security information to a camera or scanner peripheral device 115 of terminal 110. Code processing manager 111 the decodes the security information as the operations/commands that are required to be processed on terminal 110 to resolve the problem (which was encountered) and provides the security information to code verifier 112. Code verifier 112 authenticates the security information and logs the security information in a log on terminal 110.

Once code verifier 112 has authenticated the security information, code processing manager 111 provides the operations for processing to peripheral driver agent 113. Peripheral driver agent 113 includes an Application Programming Interface (API) to issue driver commands/operations directly to the peripherals 115. The peripherals 115 then processing the operations/commands provided by peripheral driver agent 113. Required acknowledgments for any calibration or settings applied by peripherals 115 during processing of the operations are presented to the operator of device 130. The acknowledgments are recorded in a log for auditing with the verified security information. The code may also be stored in the log for auditing.

The system 100 permits traceable and auditable operations for component resolution of peripherals 115 associated with transaction terminal 110 to be automatically identified and processed through code agent 131 by an operator that does not have to be a skilled or licensed technician of terminal 110. Because of the traceability, verification, and auditability of the above-mentioned process, regulations and support agreements associated with terminal 110 can be maintained while using a less skilled or any staff associated with a retailer of terminal 110 to quickly and efficiently resolve component problems of terminal 110. In this way, terminal 110 can experience higher availability to customers of the retailer, since skilled technicians are not required for certain component resolutions to be physically present at terminal 110.

In an embodiment, the code produced by code generator 122 is a QR code that includes implicit features as the security information. The implicit features are only detectable when code verifier 112 applies an infrared filter to the presented QR code by code agent 131. In an embodiment, the implicit features are color attributes embedded in the QR code. In an embodiment, terminal 110 includes an infrared light source that illuminates the display screen and QR code presented on display of the mobile device 130 by agent 131 before capturing an image of the QR code. The QR code includes explicit information that comprises the operations and metadata settings for any calibration of the peripherals 115 defined in the operations. The implicit information is used to authenticate the security information. In an embodiment, the color attributes exposed by the infrared filter to the code verifier represent an encryption of specific security information, such as an identifier for code generator 122, an identifier for device 130, an identifier for terminal 110, identifiers for the operations, and/or keys or digital signatures for server 120 and/or mobile device 130.

In an embodiment, the code produced by code generator 122 is an NFC encoded data structure that includes explicit information representing the operations and metadata calibration settings used by the operations for a specific peripheral 115. The NFC encoded data structure also includes implicit information representing the security information, which may be encrypted, and which may include identifiers, keys, and/or digital signatures as discussed above with the QR embodiment of the code.

In an embodiment, once an operator uses code agent 131 to convey the code to code processing manager 112 and the code is verified by code verifier and the operations are processed on peripherals 115 by peripheral driver agent 113, terminal 110 may still be experiencing problems with the corresponding peripheral 115 or with a different peripheral 115. In such embodiments, event agent 114 sends the appropriate events indicating the problems and event manager 121 re-maps the new events to a new set of operations and/or meta data having new settings for the same peripheral 115 that originally experienced problems or for a different peripheral 115 that is now experience a problem after the initial operations were processed to resolve the first or original problem. Code generator 122 generates a new code with encoded operations and metadata, provides to operator manager 123, and operator manager 123 sends to code agent 131 of mobile device 130. The operator then uses code agent 131 to communicate the new code to code processing manager 111, and the process repeats. This ensures that multiple problems can be resolved with just the presence of a non-technician operator or employee of the retailer, each problem resolved in an automated fashion that does not require a skilled technician, and each problem resolution logged for authenticity, verification, and auditability to comply with any regulations and support agreements associated with terminal 110.

In an embodiment, the operations are encoded in the code with appropriate calibration settings for peripherals 115 associated with measuring a good being purchased from the customer, such as a weigh scale, a fuel pump, and others.

In an embodiment, the operations are encoded in the code with appropriate calibration settings for a peripheral 115 associated with a touch-screen display of terminal 110.

In an embodiment, the operations are encoded in the code for peripherals 115 associated with a receipt printer of terminal 110, such operations can include forcing a media ejection that may be jammed in the receipt printer.

In an embodiment, when code processing manager 111 obtains a code from device 130, code processing manager 111 places terminal 110 in an administrative mode of operation. That is, code processing manager 111 upon identifying that the code is of a type that includes component resolution operations and/or corresponding metadata calibration settings for a given peripheral 115 takes transaction terminal 110 from a customer transaction mode of operation to an administrative mode of operation during which terminal 110 allows administrative operations on peripherals 115.

In an embodiment, code processing manager 111 identifies operations, peripherals 115, and parameters used by the operations from the code from the encoded data of the code. The parameters can include metadata, such as calibration or other settings that are to be applied by the operations on a given peripheral 115. Driver agent 113 uses an API of the appropriate peripheral 115 and the parameters to issue the operations and parameters to the peripherals 115 for execution by processors associated with the peripherals 115. In an embodiment, the operations and parameters are processed by a driver the executes on terminal 110 to configure and resolve a problem on the given peripheral 115.

In an embodiment, code processing manager 111 identifies a reference to a file or document within the encoded data of the code. The reference may be resolved locally on terminal 110 to obtain the file or document or the reference may indicate that the file or document is to be obtained from event manager 121 and/or from code agent 131. If the file or document is identified as an external reference (external to terminal 110) and associated with device 130, an interface screen may be displayed on terminal 110 instructing operator of device 130 on how the file or document can be provided to code processing manager, such as through wireless transmission and or by presenting an image of the file or document to a camera of terminal 110. The file or document may be associated with calibration settings for a given peripheral 115 and obtained by code processing manager 111 as a parameter required by an operation represented in the encoded data of the code. In some cases, as was discussed above all necessary calibration settings may be embedded in the encoded data of the code itself.

In an embodiment, terminal 110 is a Self-Service Terminal (SST), a Point-Of-Sale (POS) terminal, a kiosk, or a Self-Service checkout terminal.

In an embodiment, mobile device 130 is a laptop, a tablet, a phone, or a wearable processing device.

In an embodiment, server 120 is one of a collection of servers 120 that logically cooperate as a cloud processing environment (cloud).

In an embodiment, terminal event manager 121 automatically initiates the above-noted processing once an automated attempt to resolve a problem with a peripheral 115 of terminal 110 fails because of a regulation or support agreement requirement that the needed operations required skilled support staff to be present at terminal 110 for execution of the operations and verification of any applied settings by a person present at terminal 110 after execution of the operations.
